BICYCLE-BRUSH.

ffiPECIIEICATION forming part of Letters Patent No. 668,168, datedFebruary 19, 1901.

Application filed February 23, 1900. Serial No. 6,276. (No model.)

To all whom it may concern:

Be it known that I, PEMBERTON DUDLEY, a citizen of the United States,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented a new and Improved Bicycle-Brush, ofwhich the following is a full, clear, and exact description.

My invention relates to brushes for cleaning the tires of bicycles andthe like, and thus removing therefrom substances injurious alike to thetires themselves and to the floors, carpets, furniture, &c., with whichthe tires are adapted to come in contact.

The object of my invent-ion is to provide an easily-operated andefficient brush for the above-indicated purpose, in the construction ofwhich provision is made for avoiding hard wear and deformation of thebrush and for minimizing the diiference in action upon wheels ofdifierent sizes.

To this end my invention consists in the particular construction andarrangement of parts hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan of my improved brush; and Figs. 2 and 3 are sectionalelevations thereof on lines 2 2 and 3 3, respectively, of Fig. 1.

The brush comprises a base, a support for the bicycle-wheel, and brushesadapted to engage the tire while it rests upon the support and revolves.

The base consists of a board A and of two parallel vertical walls A, inwhich are journaled at the ends, as at B, parallel rollers B. From thewalls A project inward the side brushes 0, between which is left aspaceabout equal to the width of a bicycle-tire, and the bottom bristles C ofthese side brushes are longer than the others, as clearly shown in thedrawings. Between the side brushes C and the supporting-rollers B thereare secured to the board A bottom brushes D, projecting upward to thelevel of the bristles O or a little higher, and the exterior rows ofbristles D are longer than the others. It will be observed that the sidebrushes 0 and bottom brushes D surround a free central space E. Theupper surface of the rollers B is somewhat higher than the upper surfaceof the bottom brushes D.

Fig. 2 illustrates the mode of using my improved brush. Here the tireFof the wheel F rests upon the rollers B and also engages the brushes Oand D, the outer surface or tread proper of the tire being engaged bythe long bristles O and by the bottom brushes D, while the side surfacesof the tire are engaged by the long bristles D and the side brushes 0.It will be observed that but little weight comes on the brushes, as therollers 13 act as a main support of the Wheel, and thus the brushes areprotected against deformation and excessive wear. By turning the wheel Fabout its axis the tire F will be cleaned thoroughly. As'the centralspace E is free, a diflt'erence in the diameter of the wheel will notaffect the operation of the brushes materially, since it will be obviousthat a difference in the size of the wheel will show its effect mostlyat a point midway between the two supporting-rollers. Similarly thedevice will work with substantially equal effectiveness upon tires ofdifferent sizes.

Various modifications may be made Without departing from the nature ofmy invention. Thus while I prefer to make the supports B rotatable, asdescribed, I may glue or otherwise secure them rigidly to the side wallsA of the base. In this case, however, the friction opposed to therotation of the wheel would be increased. It will be understood that theterm brush will cover equivalents, such as mats or mops.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of the base the spaced parallelsupporting rollers, the longitudinally-alining, spaced bottom brusheslocated between the supports, one adjacent to each of the supports, theside bristles of said brushes projecting beyond the other bristlesthereof, and the transversely-alining, spaced side brushes locatedcentrally between the said supports and laterally of the space lyingbetween the bottom brushes, so that the side brushes and bottom brushesinclose a free central space, the lower bristles of the side i aplurality of rows of bristles, the lower bris brushes projectinginwardly beyond the other bristles thereof.

2. The combination with the base, of two spaced bottom brushes disposedin longitudinal alinement and each consisting of a plurality of rows ofbristles, the bristles of the outer rows projecting upwardly beyondthose of the inner rows, and transversely-alining side brushes locatedlaterally of the space lying between the bottom brushes and having tlesof the side brushes projecting inwardly beyond the upper bristles.

In testimony whereof I have signed my I name to this specification inthe presence of two subscribing Witnesses.

PEMBERTON DUDLEY.
